So I eventually had my intrinsic factor results back last week – negative. Given all the things I’ve read about the IFAB test I wasn’t particularly surprised, but of course it’s set me worrying about not getting the treatment I need i.e. no injections. I went to see my GP this morning, and she’s told me the low B12 must be down to my diet and to eat more oily fish. I pushed the issue and asked, if it is in fact my diet and I make a change in that respect, are they going to retest my B12 to see if the levels return to normal? She has agreed to another blood test at the end of this month.
I don’t really believe it’s my diet – I already eat plenty of meat, fish and dairy products, but of course I will still see if I can make any changes and maybe start taking a supplement. However, I just wondered, given I’ve already had the 6 loading doses, is this going to massively skew the results? I had my last injection on 18th December, and my blood test is 23rd February. Obviously I know they usually advocate an injection every 3 months, so presumably this is how long they think it lasts in your system, but I also know it’s different for every person, and some people self medicate on a far more regular basis. Does anyone have any thoughts? Is it still worth going for the test?
I also asked for a copy of my original test results from my blood test back in October:
Serum vitamin B12 – 110 ng/L (145 - 910)
Serum folate – 4.6 ug/L (3.0 – 20.0)
I don’t really know what to make of these yet. Can anyone comment? The folate seems within range, but at the very low end, so should I be thinking of taking a supplement for that as well? My symptoms are extreme fatigue, occasional shortness of breath, dry skin & nails, sleep problems, mouth ulcers, digestive issues and brain fogs. I’m very new to all this and still making sense of everything I’ve read, so any advice would be gratefully received. Many thanks.
PS: As an amusing aside – having chased my IF results for over 8 weeks, it was quite funny when I finally said it was getting silly and could they follow them up. Receptionist suddenly located them on the system within 2 minutes. The awkward silence when she did (having told me they can take months to come back) was rather funny. I put it down to the fact she could see they’d obviously come back weeks ago. Funnily enough, having obtained a hard copy this morning, it’s stamped “Received 13th December” – just 9 days after my test. Awesome.
